Javascript 反应本机：闪存消息内存泄漏错误

我用的是React Native。当我导航到另一个屏幕而不等待消息消失时，会引发内存泄漏错误

代码 错误

您不需要等待flash消息消失。您可以在导航到新屏幕之前以编程方式隐藏消息

代码

具有useffect（）的解决方案

这个库有清理方法吗？我不这么认为。侦听器和异步操作通常需要清理，我似乎找不到类似的方法。你能分享更多你想要实现的目标吗？@VinaySharma不，这个库没有清理方法。如果我不等待flash消息消失，然后转到另一个页面，我会收到此错误。您是否在全球范围内使用它？

showMessage({
  message: "Hello World",
  duration: 2000,
  description: "This is our second message",
  type: "success",
});

Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in %s.%s, the componentWillUnmount method,

// import hideMessage method from the library
import { hideMessage } from "react-native-flash-message";

// a function which navigates to another screen
foo = () => {
  // assuming you are using react navigation
  // in a class based component
  const { navigation } = this.props;

  // call hideMessage before you navigate
  hideMessage();
  navigation.navigate('ScreenName');
}

import { hideMessage } from "react-native-flash-message";


  useEffect(() => {
    return () => {
      hideMessage()
    }
  }, [])
